Method of viewing audiovisual documents on a receiver, and receiver for viewing such documents

Abstract

The invention discloses a method of viewing audiovisual documents on a playback device, comprising a step for reading or receiving a document and a display step for viewing the images of this document on a screen. The method further comprises a step for reading or receiving an attribute associated with a time band of the document. A predetermined value of the attribute triggers on the device the enlargement of a part of the image on playback during said time band, because of which this image part occupies a larger area on screen.

Description

[0001]This application claims the benefit, under 35 U.S.C. 119, of French patent application No. 0452076 filed 17 Sep. 2004.FIELD OF THE INVENTION[0002]The invention relates to a method of viewing audiovisual documents on a receiver, and a receiver for viewing such documents. The invention more specifically relates to the processing of the document display.BACKGROUND[0003]These days a user can download an audiovisual document from a broadcaster to view it on his playback device. More recently, new miniaturized devices for playing back audiovisual transmissions have appeared on the market. Thus, personal digital assistants (PDAs) or even mobile telephones with color graphics screens, are provided with programs and memories for storing audiovisual documents, such as films, documentaries, sporting events, and so on. When the part of interest to a user concerns a small part of the image, the miniaturization of the screen makes it difficult for the user to follow the event.[0004]Associat...

AI Technical Summary

Benefits of technology

[0008]In this way, the user can easily view actions of interest, even on a small screen. Furthermore, the playback device itself determines the characteristics of the area to be enlarged according to the content of the image. In this way, the display is customized for each receiving device. According to a first improvement, the device determines the geometric characteristics of the area to be enlarged. According to another improvement, the device itself determines the enlargement ratio of the area according to the characteristics of the display means, a mobile telephone screen for example. In this way, the area to be enlarged is tailored to the device. According to another improvement, the image is analyzed to determine the position of one or more particular objects, a ball surrounded by a number of players, for example. The duly delimited area around said object will then be enlarged.

Problems solved by technology

When the part of interest to a user concerns a small part of the image, the miniaturization of the screen makes it difficult for the user to follow the event.

However, in the case of devices with miniaturized screens, adapting the display to the screen size does not always make it possible to follow the event in satisfactory conditions.
